Description
Technical field
The invention belongs to field of chemical engineering, it is related to a kind of uniform distribution device of tower gas-liquid contanct equipment and application thereof,
More particularly to a kind of uniform distribution device of tower gas-liquid contanct equipment and its use that uniform gas distribution is realized by increasing air chamber resistance
On the way.
Background technology
Chemical reaction process is often referred to tower gas-liquid contanct equipment, it is necessary to realize that bubble is dispersed in liquid phase,
This not only needs bubble dispersed phase in unit height of mass transfer to be uniformly distributed, and needs the diameter of bubble dispersed phase homogeneous.
Uniform gas distribution method and apparatus on gas-particle two-phase reaction more to be had been reported that, patent CN 10250867A and CN
202621144U proposes a kind of uniform distribution device of the material suspended fluidization reaction of solid granular, but the gas distribution is filled
Put the bubble for not being suitable for producing homogeneous diameter in a liquid.
Patent CN 102728283A and CN 202700473U propose a kind of uniform gas distribution side of gas-particle two-phase reactor
Method, methods described is：Cloth gas port is opened up on the wallboard of hopper, cloth gas port is elongated openings, it is possible to resolve unit mass transfer in device
The uneven problem of height gas pressure distribution, makes solid particle material fluidization in device dispersed, but the device cannot
Realize that air pressure is uniformly distributed in a liquid, long and narrow cloth gas port perforate easily produces larger-diameter bubble, it is impossible in a liquid
Uniform gas distribution.
Patent CN 202289881U disclose a kind of outer membrane pressing filter of gas distribution uniform in a liquid.In a device,
The device of even gas distribution is one group of aeration tube, and for the disturbance on membrane filtration processes strengthening membrane surface, the surface to film is cleaned.But
It is that, for the occasion for producing the requirement of bubble uniformity coefficient strict, this gas distribution mode is inapplicable.
Patent CN 202844893U disclose it is a kind of by sand head, main flow of gas pipe and drop-leg constitute it is quick
Even distribution device.This device effectively increases the distribution density of the bubble within fluid of unit volume, improves gas liquid reaction
Speed, has been specifically applied to petroleum industry field, but this gas distribution mode is still present into problem in use.
Reason is that this equipment is difficult to bubble and is uniformly distributed on the cross section of reactor different height, it is impossible to realize that unit is passed
The phase content uniformity of bubble dispersed phase in matter height.
Patent CN 203484063U disclose a kind of Quick uniform air-spreading disk, and its air-spreading disk is overlapped by multilayer sand net and constituted,
The area of each ventilative part of layer sand net is gradually reduced from top to bottom, and the aperture of sand net is 20 microns.But, this device is also only
Suitable for the petroleum industry of gas-liquid mixed reaction, and the homogeneous bubble dispersed phase of diameter cannot be obtained.
The difficulty of the tower uniform gas distribution of gas-liquid contanct equipment is mainly manifested in different zones generation bubble on gas distributing disc
Complexity it is different, cause the phase content of bubble dispersed phase in unit height of mass transfer cannot uniformity, and generation bubble
Diameter difference is quite big.Due to the influence of equipment wall effect, under same liquid depth, the pressure above distributing disc is uneven
It is even, cause under the conditions of identical admission pressure, closer to the regional area of reactor wall on distributing disc, easier generation gas
Bubble, and away from the more difficult generation bubble of regional area of reactor wall.Admission pressure or flow are increased, although can make away from anti-
The regional area of device inwall is answered also to produce bubble, but because flowed friction suffered by the region near reactor wall is smaller, it is raw
It is excessive into bubble diameter, cause that the bubble of homogeneous diameter cannot be obtained in tower equipment.
